PROGRAMMING:Sequence summation - enhanced version
Given a number $$a $$($$1 / Le A / Le 9 $$) and a non negative integer $$n $$($$0 / Le n / Le 100000 $$), find the sum of the sequence $$s = a + AA + AAA + / cdots + AA / cdots a $$($$n $$a $$). For example, $$s = 1 + 11 + 111 = 123 $$when $$a = 1 $$, $$n = 3 $$.
###Input format:
Enter the number $$a $$and the non negative integer $$n $$.
###Output format:
Output the value of the sum of its $$n $$item sequence $$s $.
###Input example:
```in
1 3
```
###Output example:
```out
one hundred and twenty-three
```
